Answer: 20%
Explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.
So to write 1/5 as a percent, we need to find a fraction equivalent to 1/5 that has a 100 in the denominator.
We can do this by setting up a proportion.
.
Now, we can use cross-products to find the missing value.
So we have (1)(100) which is 100 is equal to (5)(n) or 5n.
So we have 100 = 5n.
Next, dividing both sides of the equation by 5, we have 20 = n.
So 1/5 is equal to 20/100 or 20%
